not, a screw-threaded coupling equipped uiisbipping of the with said nutand effective for actuating saidfrictional clutch, and means forminconnection between said nut and said bra e-strapactuating means.

2. A machine of the character described, comprising a drill-line drum, ashaft bearing said drum, a dutch contrivance for effecting connectionbetween said drum and shaft, a band or driving wheel a frictional clutchadapted to have contact with said wheel, a shaft loosely equipped withsaid frictional clutch and bearing said band or driving wheel, meanseffecting connection between said driving-wheel and a rotary art fixedto the drum-shaft, a screw-three ed coupling equipped with a nut andeffective for action between said frictional clutch and the shaftbearing sa'id clutch, a brake-band engaging said rotary part, and alever-and-rod connection between said not and said brake-strap.

3. A machine of the character described, comprising a drum-equippedshaft having a tixed wheel, a brake-strap encompassing said wheel, aband-wheel, asecond shaft equipped with said band-wheel, a frictionalclutc loosely arranged upon the latter shaft, and

fixed to a disk or pulley, a screw-threaded coupling for said frictionalclutch equipped with a nut, means of connection between said pnllev andsaid brake strap encompassed wheel, an arm-and-rod connection betweensaid not and a lever for actuating said brakestrap.
